Question

Quizplus · Accepted Answer

Carrier proteins are involved in both active and passive processes of membrane passage. In passive processes such as facilitated diffusion, carrier proteins bind to specific molecules and help them move down their concentration gradient. In active processes such as active transport, carrier proteins use energy to move molecules against their concentration gradient. Aquaporins are a type of channel protein that facilitates the passage of water, pumps use energy to move molecules against their concentration gradient, and receptor proteins are involved in cell signaling but not membrane passage.
